Rixen and Kaul have recently released a new version of their Vario rack, the Vario Sport. It’s conveniently sized to fit a large saddlebag like my 24l Carradice Super C bag, which is 17cm deep, 21cm tall, and 33cm wide plus pockets. It also comes with straps and will fit a dry bag or other goods horizontally, rather than vertically like the original Vario rack.
